My present invention relates to means for applying a stir-face orreenforciiig strip of rubber to the out together seams of sheet rubberarticles, such as bathing caps and is in lar pocket like nature, but isnot limited to 7 any specific articles, though for convenience,

it will be described as used in the manufacture oi bathing caps.

The invention aims to provide a machine which will be power driven andlargely automatic in its nature, the operator needing only to attend tothe placing of the caps in position and the machine operatingautomatically to apply the ribbon to the seam to overlie the same andgreatly strengthen it.

The invention further aims to provide a machine in which the applyingmeanswill operate intermittently or in distinct cycles, automaticallydelivering the cap at the end of each cyc e and pausing long enough toperinitthe insertion of a fresh cap. v

The invention further aims to provide means for automatically feedingtheribbon in continuous strip iorm'in a manner to avoid undue tensionthereon and to avoid accumnlation of any excess material at or adjacentthe point of application.

-Another object is to provide automatic means for severing the ribbonadjacent the edge of the cap in such a manner as not to interfere withthe delivery thereof. 1

The invention also aims to provide a machine which will be capable, initsoperations,

of being readily controlled as to starting and stopping, in additiontoits automatic cycle of operations. I

With these, and other objects in view which will be apparent fromthefollowing description, the invention includes the novel features ofconstruction and arrangement and combi- I nation of parts hereinafterdescribed, the invetion being defined by the claims appended hereto. o

Fig. 11 is a view of the cap before the reenforcing tape or ribbon isapplied; and

Fig. 12 is a view of the cap as it appears after application'oi' saidreenforcing tape or ribbon.

At the outset it may be stated that the present machine is designedparticularly to apply reenforcing strips or ribbons to bath caps as madeby themethod and apparatus disclosed in an application filed by me inthe United States Patent Office on the 19th day of September,1929,Serial Number 415',- 544, the cap material being conveyed from the diepress of said application by a suitable table conveyor past operatorswho remove the cut caps from the stock sheettion in the reen'forcingmachine.

)erator picksfthe cap for inser- I Such table conveyor is indicated at1, beinga flat endless belt passing over a supporting table and drivenin any suitable manner by means not shown inasmuch as the same forms nopart of the present invention.

The cap when lifted from the conveyor. is placed by the operator on whatI may term a carrier roll 2 which is of approximately disk from andwhich has coacting therewith a yieldingly mounted presser roll 4likewise of disk form.

The press-er roll or disk has channeled periphery and the carrier rollor disk of correspondingly shaped periphery of male formation to coactwith the female formation of the presser roll, these peripheries beingpreferably of V and wedge shape respectively as shown. In applying thecap to the carrier roll, it is held with its open edge opened out anddirected forwardly and is slipped over the front edge of the roll 2 intothe position shown in Fig. 1 where one end of the seam abuts against orlies closely adjacent to, the end of the guide 80 for the ribbon R whichis fed to the guide in the manner hereinafter particularly described.

The cap is of course applied to the carrier roll while this is at restand when so positioned is ready to have the end of the seam pass intothe bight of the carrier and presser rolls along with the reenforcingstrip or ribhen, the entire length of the seam being carried throughbetween the rolls by one rotation thereof and the ribbon being likewisecarried therethrough and applied to and rolled down upon the seam andeffectually welded thereto due to the nature of the un vulcanizedmaterial of which the caps and ribbon are made.

At the end of the ribbon applying and rolling down operation, the rollswill come to rest at which time, the position of the cap will bereversed in that it will embrace the rear half or portion of the carrierwheel instead of the front half, thereby leaving the front half orportion ready for the application of a fresh cap.

Shortly after the beginning of the next cycle of operation cuttermechanism hereinafter described, severs the ribbon or tape R between thepreceding and succeeding caps whereupon the preceding reenforced capwill drop off or away from the roll 2 by gravity and drop into anopening 5 of hopper shape formed in the table 6 onto a transversehorizontal conveyor 74 By belt 7, the caps are conveyed to and droppedonto a trap door 8 which is counterbalanced just sufficiently to beoverbalanced and operated by the weight f the cap. A Trap door 8 isconnected to operate suitable counting mechanism 8a. After leaving thetrap door, the article falls on the lower end of an inclined elevatingconveyor 9 which delivers it to the main conveyor 1 of ti e systemreferred to.

By severing the tape or ribbon at con:- mencement of the reenforcingoperatien, I ensure that the tape will. be in proper position betweenthe bight of the rolls for accurate application to the succeeding cap,as there is no loose end to be accidentally displaced.

Power is applied to operate the i achine from an individual motor 10(pre rably electric), which drives the main shaft 11 throughtransmission means such as belt 12 and belt pulleys 13 and 14:, theformer being fast on the motor shaft and the latter con nected to shaft11 by clutch means for connecting and disconnecting the drive.

The clutch means is shown in detail in Ni 4 wherein it will be seen thatpulley l rotatably mounted on shaft 11 between v 14a fast on the shaftand an opposed disk l-lo having a hub splined on the shaft and providedwith an annular groove to eng: re the pins of a shifter fork formed as ap; bell crank lever 92 fulcrun'ied on a fined pivot and having its arm92a. connected by link 91 with an arm 89a. fast on a rock shaft 901;carried by standards 90 beneath the machine table or frame, which rocksha ft carries a flu 11 win,

treadle lever 89 located within convenient reach of the foot of theoperator.

Disk 1% is normally pressed into contact with pulley 1 1 by spring 140encircling the projecting end of the shaft between the hub of the diskand an abutment disk 14:55 secured to the end of the shaft, so that thedrive normally connected but. capable of being dis connected at will bypressure on treadle 89.

Shaft 11 has fast thereon a worm 15 which meshes with a worm wheel 16which keyed or otherwise suitably secured. to a shveve 1? rotatablymounted about a transmission shaft 18 to which the carrier wheel 2hereinbefore referred to is rigidly connected in the manner hereinafterdescribed.

Sleeve 17 has affixed to its opposite end cam member 20 provided with acam groove 21 in the face thereof designed to operate clutch means toimpart intermittent ro -y motion to shaft 18 and carrier roll or disk 2.

For this purpose, I provide a bell crank lever 22 articulated on a fixedpivot 23 on the gear casing or housing and having one arm provided witha roller 24. engaging the cam groove 21 (see Fig. 5), while other z.-.i'l carries a roller 25 designed to coact wnh either of a pair of camprojections 26a of clutch member 26 splined on a counter shaft 29 anddesigned to coact with clutch member 28 forming a part of or rigidlyconnected with a gear 28a both clutch 28 and 28c being rotatably carriedby counter shaft 29 through the intermediary of sleeve 80.

The gear 28a has teeth designed to mesh with the teeth'of worm gear 16whereby said a gear 28d and .clutchrmember' .28 are drivencontinuouslyexcept whentreadle 89 is operated to disconnect the motivepower as before explained. I 7

Fast on shaft 29 is a gear 31 which meshes with a gear 32 fast on theshaft 18 whereby said shaft18 and carrier rollor disk 2 will be drivenonly when clutch members 26 and 28 are in engagement.

Cam groove 21 is so designed that roller 25 will be moved out of thepath of cam projections andheld in such position for a long enoughperiod to permit shaft 18 to make one complete rotation, the clutchmembers .26'-28 beingautomatically engaged at such time by-the a'ctionof spring 27 on sliding clutch member 26, and to disengage the clutchmembers by the action of roller 25 on one of the cam projections 26a andhold them Qout of engagement and hence the shaft18 and carrier roll ordisk 12 stationary for a period sufficient to enable the operator toapply a fresh cap for roenforcement as hereinbefore described. Lv

The drive gear housing 33 is suitably affixed to or carriedby the tabletop and has affixed to its front face and forming virtually a part'hereof a casing member 34 which carries a cam ring 35 encircling theshaft 18 andprovided with a face cam groove 36 for actuating the ribboncutting mechanism hereinbefore mentioned. This ribbon severing mechanismis 'carriedby a-carrier head 19 for the wheel or disk 2 and due tobathing caps being of pocket shape andopen only on one side, saidcarrier head is of approximately U-shape as shown in Figs. 2 and 3,having one arm (19) secured to the shaft and the other arm 19a spacedtherefrom and having the disk or roll 2 rigidly secured thereto by meanssuch as ascrew bolt as shown,-'said roll or disk 2 being arranged inaxial alinement with said shaft 18.

The disk or roll 2 has a radial :slot or recess 2a in its periphery inwhich normally rests (bene'aththe ribbon. or tape), a shear or cutterblade 37. which coacts with a shear or cutter blade 38, the two formingin effect a pair of shears, having a common pivotal axis at 39.

Blade 37 is carried by an arm 42 pivotally mounted on the portion of thehead 19. which 'connects the two arms thereof so as to swing about axis39 in a plane coincident with said slot 2a and a tension spring 47connected with said arm tends to swing it in a direction to move it'outof the slot and towards the other shear memberl 38. *Saidshear member 38is carried by an; arm 43 mounted on the head to swing about the sameaxis 39 as arm'42, and said arm 43 has fast thereon, concentric. withits axis, a gear 44 which meshes with ara'ck 45 slidably guided on theback face of the carrier member 19 and which rack'carries a roller $5?)which engages the Fig. 6).

cam groove 36 in the cam member" 35 i (see The rack has affixed to theend thereof an arm 46 having an inwardly inclined portion provided withan adjustable contact screw designed to contact with a pin or abutment41 on thearm 42. The result of this arrangement is that while the head19 and disk 2 are rotating and the roller b is trav-' eling around theconcentric and low portion of the cam groove, the slideor' rack will-beheld inits innermost position and the shear blades separated as shown inFig. 3 due to the action of gear on the rack and the action of arm 46 onblade arm 42. When the roller 5 travels through the high ornon-concentric part of the cam groove the slide will first he movedoutward which will cause'the'gear to rotate to swing arm 43 and blade 38downward towards blade 37, and which will simuli y taneoussly removerestraining arm 46 whereby blade arm 42 Will be swung outward by itsspring 47 and thus the shears will be brought together to sever the tapeat the time in the cycle of operations heretofore referred to. As theroller moves inward towards the concentric portion of the. cam groove,the reverse operation will take place and the shears restored to normalopen position.

The unvulcanized rubber tape used for seam ieenforcement purposes is ofsuch a character that I find the best results are secured by feeding itfrom a pile or accumulat'ion of slack loops rather than direct from therolls on which such material is wound a at the time of manufacture.

To enable this to be done without the accumulationof too much slack, Iprovide the following mechanism.

A slack tape receiveris'providedin the I shape of a small box orreceptacle 54 which is rigidly carried by a lever 55 fulcrumed at 56 to-a bracket arm 57a of the vertical bracket or standard frame 57 carriedby the table and provided with adjustable counterweight 1;;

ported by brackets or standard on the table from which the tape passesover guide 59a between suitable guide pins and thence to and betweencoacting feed-rolls 60'and 61 from.

which it descends into the receptacle 54.

The roll 60 is eccentrically mounted on L;

shaft 60a journaled 'at the upper 'end of standard'57 and is driventhrough sprocket 62 fast on said? shaft, chain 63, sprocket 64 on shaft6 1a journaled in an extension of said standard beneath the table, whichshaft carries gear 65 meshing with gear 66 to secure reversal ofmovement; Gear 66 is fast on a short shaft also journaled in saidstandard 57 which is driven by sprocket 67 and chain 68 froma sprocket69 on shaft 76 which is driven by bevel gears 71-72 from the shaft 7 3of the horizontal belt conveyor 7 which moves continuously.

Reverting to the ribbon feed roll construction, the lower roll 61 is anidle roll andis preferably provided with a felt covered rim or peripheryfor frictional engagement.

Said wheel 61 is journaled on a substantially horizontally disposedcarrier arm 74 ivoted to an olfset or lateral extension 57a 0 standard157 to provide a floating support for the rol The free end of arm 74 haspivoted thereto a dog 7 40 designed to yield or move in an upwarddirection only relative to arm 74, and said free end of arm 74 isconnected by tension spring 74?) with the an arm 7 40 projecting fromthe top of the standard.

By this arrangement, the roll 61 is normally yieldingly pressed intocontact with the eccentric roll and asthe latter revolves roll 61 willbe moved up and down and carrier arm 74 swung to a degree correspondingto the eccentricity of roll 60.

An arm 75 fulcrumed on a bracket extension 57?) of the standard has anangularly turned end 7 5a designed in one position of the arm 75 tooverlie the dog 74a and contact therewith and in another position to lieoutside the path of said dog as it is moved up and down by the action ofthe eccentric roll. The free end of arm 75 is connected by link or rod76 to apivot block 55a adjustably fastened on the pivoted rod 55 whichcarries the receptacle 54.

The counter balance weight 58 is so adjusted as to be overbalanced bythe receptacle 54 when the desired amount of slack is accumulatedtherein, and to raise said receptacle when there is an insufiicientsupply of tape thereon. lVhen this latter occurs, the dog or projection7 5a will be moved out of the path of the dog or pawl 74a and thefloating roll 61 will remain in contact with the eccentric roll throughits entire cycle of movement and a maximum feed of tape will result.

This will increase the supply in the receiver until. the weight thereofis sufficient to depress the receiver which will pull down on red 76 andswing dog 7 5a into position to contact with dog or pawl 74a.

Should the floating roll be in its upper position at the time of suchmovement, downward movement of arm 74 and pivoted dog 74a will cause thelatter to pivot on contact with dog 7 5a until it rides past the latterand drops into engaging position below the same. As the eccentric rollcontinues: its rotation and its surface recedes upwardly, the floatingroll will be prevented from following and thus the feed will be stoppedfor a portion of the cycle of rotation of the eccentric roll and thiswill continue until the amount of tape in the receiver has been againdepleted.- A spring brake finger 77 is provided to bear against the sideof roll 61 to prevent overthrow.

A guide casing 78 is mounted just above the box 54 to assist in placingthe ribbon therein and across the upper portion of this guide casing isa pin 78a over which the ribbon is drawn, and through suitable guides 79and 80 to the point of contact with the bath cap.

The pressure roll or disk 4 is mounted on the free end of a springpressed lever 81, which is fulcrumed in a yoke-shaped bracket 82 fixedto the table top, and is provided with a lever 83 fulcrumed near itsbase, one end of which is connected to a strong spring 85, and its otherend provided with a hand wheel screw 86 to vary the tension of thepressure disk to its work.

The pressure disk 4 may be lifted clear of its engagement with the disk2 by operating the handle 87 to elevate its cam 87a under the lever 81.

To protect the operator andalso to assist in the proper guiding of thebath cap in its rotation with the disk 2, the guard plate 88 isprovided, by mounting it on the lever 81.

By the use of the clutch controlled by the foot pedal 89, the mechanismmay be stopped at any time in its cycle of automatic action where thisis desired due to misplacement of cap or other reason, such stopping inno way disturbing the timing of the cycle.

The inclined conveyor 9, hereinbefore referred to, forcarrying thereenforced articles up to the main conveyor 1 is preferably driven fromshaft by means of sprocket 93, chain 94 and sprocket 95.

In order to drive the belt conveyors 7 and 9 and the ribbon feedingmechanism a sprocket 52 is mounted on the quill 17 previously describedand which it will be recalled receives continuous motion from theelectric motor. A shaft 50 is mounted in bracket 50a below the table andcarries the sprocket 51 and the bevel gear 49 fixed thereon (Fig. 3). Achain 53 drives sprocket 51 from sprocket 52. A bevel gear 48 is mountedon one end of shaft 73 previously described and meshes with the gear 49.The means by which the ribbon-feeding mechanism and conveyor belt 9 aredriven from shaft 7 3 have previously been described. Through this trainof mechanism the ribbon feeding mechanism and belts 7 and 9 are drivencontinuously, except when pedal 89 is depressed.
